how to check system specifications?


Hello,

Are there commands in linux to check the specifications of a computer such as;

- CPU type (AMD, Pentium, 32/64bit), support, such as max cycles/frequency, etc.

- RAM support, max capacity, spec such as PC100/PC133/etc.

etc.

I tried dmidecode, but it says:
bash: dmidecode: command not found

Any idea?

try dmidecode as root, also look in the /proc directory it contains all the system info for example, as root:

cat /proc/cpuinfo

gives me the following:

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 9
model name : Intel(R) Pentium(R) M processor 1500MHz
stepping : 5
cpu MHz : 600.000
cache size : 1024 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe est tm2
bogomips : 1195.31
clflush size : 64

its all in /proc

Cheers

Chris.

Hey,

ifconfig has to be run as root, you can become root in a terminal either by:

su

and then entering the root password, you will be root in that terminal though until you close it or exit. Or you could set up a program like sudo or fakeroot so when you want to run a root only command you prefix it with sudo. i.e.

sudo ifconfig

I'm not sure why you trying to run the thread command - I don't think it is a command, it isn't a command on my system. reddazz was pointing you in the direction of other forum postings.

The ./ prefix makes bash look in the current directory your in for the executable file, for example if I wanted to run an exe program that was in my current directory I would enter:

./exe_program_name

Hope that makes sense,

Chris.

I had a same problem.

I tried dmidecode on other than root account it says
command not found.

In terminal I run dmidecode with su still i got command not found.

Then i tried the following and it works for me.

su
password:

/usr/sbin/dmidecode and it works fine for me.

I prefer the output of lshw to that of dmidecode.

lshw takes the info from dmidecode and several other sources puts it all togethert and formatis it a bit nicer, so it is easier to read.

lshw will most likely not be installed on your distro by default, but it should be readily available in it's repository..

NO matter which tol you use (lshw, dmidecode, cat /proc/cpuinfo) having a list of the CPU feature flags handy to decode the CPU capabilities is pretty handy..

Code:
